Carotenoid 1,2-hydratase

Carotenoid 1,2-hydratase (, CrtC) is an enzyme with systematic name lycopene hydro-lyase (1-hydroxy-1,2-dihydrolycopene-forming). This enzyme catalyses the following chemical reaction


 * (1) 1-hydroxy-1,2-dihydrolycopene $$\rightleftharpoons$$ lycopene + H2O
 * (2) 1,1'-dihydroxy-1,1',2,2'-tetrahydrolycopene $$\rightleftharpoons$$ 1-hydroxy-1,2-dihydrolycopene + H2O

In Rubrivivax gelatinosus and Thiocapsa roseopersicina both products are formed.
